Crestron MP-AMP30 Media Presentation Audio Amplifier

Media Presentation Audio

Amplifier: MP-AMP30

Introduction

The Crestron

MP-AMP30 provides a convenient, low-cost audio amplifier solution

for a variety of applications. A perfect complement to the entire Media Presentation

line from Crestron, it features a compact surface-mountable design that installs

virtually anywhere without requiring an equipment rack. High-efficiency Class D

circuitry delivers 15 Watts per channel to drive one or two pairs of 8-Ohm speakers,

or a single pair of 4-Ohm speakers, making it ideal to support stereo speakers at the

front of a room or mono speakers in the ceiling. Mono-summed operation is enabled

by changing two jumpers on the front panel.

Refined, reliable operation is ensured thanks to pop-free turn-on circuitry and

electronic short-circuit and overload protection. An energy-saving design achieves

optimum efficiency under load, and powers down automatically when no input

signal is detected for more than five minutes, reducing overall power consumption

and heat as part of a green system design. Its extruded aluminum housing is both

attractive and effective at dissipating heat, affording a silent running design without

cooling fans.

Features and Functions

• Compact surface mount power amplifier

• 15 Watts per channel into 8 or 4 Ohms

• Stereo or mono-summed operation

• High-efficiency Class D topology

• Energy saving design reduces power consumption when idle

• Convection cooled for noiseless operation

• Simple volume, bass, and treble adjustments

• Built-in loudness contour circuit

• Electronic short-circuit and overload protection

• Detachable terminal block speaker connections

• Unbalanced RCA line inputs, 3-foot (~0.9 meter) cable included

Installation and setup of the MP-AMP30 is simple. Detachable output connectors

facilitate the termination of speaker wiring up to 16 gauge. RCA inputs connect

directly to the line output of a video projector or display, audio processor, mixer, or

AV switcher. Rotary controls provide for adjusting the overall speaker volume, as

well as bass and treble. For quiet environments, loudness compensation is employed

by setting the volume control below the center detent position.
